Hi all, I've changed tracks a little, was experimenting with capacitor dumping methods and i am now experimenting with the Stingo oscillator from Sucahyo.
If you are out there Sucahyo, please visit this thread and let us know what you are up to.
The results with the battery charging circuit, with the modified capacitor/full wave bridge have been very promising so far.
I purchased a new 12 volt FVP flooded lead acid lawn battery for testing.
The battery right from the store showed 12.46 volts and after a couple cycles, discharging down to 12.60 volts loaded voltage and then recharging with oscillator, after letting battery rest overnight, the battery now sits at around 13.00 volts.
And the loaded discharge voltage is holding at a higher level.
I think the circuit has been de-sulphating the battery and will make it closer to new.
And it is not surface charge, that is for sure.
I was able to charge the battery up to 15.40 volts, although John Bedini said, that 15.60 volts or 2.60 volts per cell, is the ideal charging finish voltage, to be sure all sulphates are reintegrated back into the electrolyte, thus allowing the battery to last 15 years, rather than 4-5 years.
I will be posting the circuit drawing i am using at the moment and a picture of my "physical" setup here.
All comments welcome.

Hi folks, here is the schematic.

Thank you so much SkyWatcher123 for sharing。
PNP Transistor emitter On top. It doesn't matter.

The two-wire coil, similar to the Tesla pancake coil, increases the coil's own capacitance.
This slows down the rise of the coil's back EMF when the transistor is closed.
Maybe it works better.

Looking forward to your introduction of the best results.

Thank you

Hi panyuming, the pnp emitter is correct in the drawing, this way it draws 1/4 of the current, compared to the pnp emitter in the normal way and gives the same output.

Good. It just works fine.
The usual transistor is used in reverse, and the magnification decreases a lot,
mainly because the reverse withstand voltage is about 6~8V.
Your TIP142 is a Darlington transistor,
so the reverse withstand voltage exceeds your 12V supply voltage.
Yes, it can be used.

Thank you again for sharing and wish you success!

Hi panyuming, yes it works well enough.

Experiments shall continue.
All comments welcome

I'm going to put this thread of yours and other threads that charge the battery with pulses.
Classified as a Bedini device.

Previously I studied Bedini device.
See that many points are included:
1. The effect of rotating wheel magnet passing through the coil.
2. Multi-stranded wire and 7 transistor driven coils.
3. The speed of the reverse peak voltage rise when the coil is cut-off.
4. Charge the battery with the reverse peak voltage of the coil.
5. Charge the capacitor with the coil reverse peak voltage.
6. Charge the battery with capacitor discharge.

I can't guess which of them causes the OU effect.
I have only experimented with charging lead-acid batteries with coil fast reverse peak voltage.
No OU phenomenon was measured.
Because I heard that fast pulses can elicit 'radiant energy'.
I spark the lead-acid battery directly.
Think this is the fastest pulse I get along with.
The OU phenomenon was also not measured.

Learn to copy someone else's device,
It may be only a little bit closer to success.

I heard a story from the 1940s.
There is a company that can make very good large lenses.
In addition, corporatization buys their secrets at a high price.
Inform after the transaction: non-stop stirring.

So I envy your hard experimenters who get the OU effect.

Yes, common academia accredits Bengt Wahlqvist, but it was in fact
John Bedini that invented the pulse charger, more than 40 yrs ago.


As per your list of qualities:
None of those are the secret sauce.


If you truly want to understand:
Place a child on a swing and push them


What makes Bedini’s devices do what they do is sympathetic harmony.
The pulses are timed to the rpm. This is key


small impulse to keep the momentum going
energy generation, based on momentum
NOT applied force!


Back EMF is fighting the momentum
not fighting the impluse


This is MUCH different than a direct drive motor.
Wherein the back EMF is constantly fighting the driving force.


Bedini’s machines are an electrical analogy to William Skinners gravity drive.
The main difference being the potential well that is drawn from.

Hi all, I have modified the circuit a bit.
The only thing changed, is the oscillator is between the negatives, like the rene-emf charger circuit.
Though still using the stingo oscillator circuit, with just a single diode off NPN collector to positive
of charge battery.
The positive of 19.5 volt input is connected to the 12 volt positive of charge battery.
So the oscillator is only seeing the voltage difference between the input voltage source and the
charge battery voltage, or 7.5 volts and varying.
This circuit change has boosted output and efficiency.
Also planning to build much larger coil, to experiment with.
The other benefit, is this style of circuit, can still be used to charge 1.2 volt nimh cells, as the
potentiometer can be adjusted to lower input power levels.
Experiments continuing.

Hi all, I'm not sure why the Stingo/rene-emf style charger is not charging the battery as well as the standard
Stingo, with modified full wave bridge combiner.
Though that is what I'm observing, so here is the circuit i am testing at the moment.
I moved the potentiometer to the PNP base connection, this frees up the clutter on the NPN base
connection line, for better base triggering.

Hi Rama, The coil is two layers of 18awg. magnet wire, the layers are bifilar wound, meaning, two 18awg. magnet wire strands coiled at the same time, until you have two layers.
Then, the bottom bifilar coil layer is wired in series, same with the top bifilar coil layer, then each of those bifilar coil layers are wired in series with each other.
All coil strands are wired so magnetic fields compliment one another, meaning no bucking of magnetic fields in this design.
Any ultra fast diodes should work fine.
The emitter of the NTE52 NPN is connected to the input power supply negative rail connection.
I will be continuing experiments again, and i will be focusing on using the speaker wire, spiral pancake coil for an oscillator design, as i feel with the right circuitry, we may be able to observe some resonant effects.
Here is a picture of the ferrite toroid stacked core and coil, with the 18 awg. speaker wire pancake coil underneath, not in use at the moment.
